问题 In the 1980’s the rate of increase of the minority population of the United States was nearly twice as fast as the 1970’s.
选项 A、twice as fast as
B、twice as fast as it was in
C、twice what it was in
D、two times faster than that of
E、two times greater than
答案 C
解析 twice一般用于数量上的翻倍，仅可以说，twice as much as，or twice as many as，但绝不可用于对形容词或副词“翻倍”，如twice as fast as，twice as rapidly as。因此，A、B是错的；E中未补出比较对象，会产生歧义。C比D简洁，what从句相当于名词；it指the rate of increase。
